I-I'm alive everyone! And I wrote a long chapter for you. (2k is long for me, okay?)

Greg Lestrade leaped onto the American wielding the knife. For a man of such small stature, Lestrade handled himself well against Sam. He pinned Sam's shoulders long enough to swing the cuffs on.

"You're making a mistake!" Sam insisted. "I'm not the enemy!"

"In all honesty, I'd love to agree with you," said Lestrade. "But you are the one holding the knife."

"Look, he wasn't going to do anything, officer," Dean tried to defend his brother.

"That's Detective Inspector to you, boy," Lestrade snapped.

"The tall one isn't the only one guilty, Greg!" Sherlock cried, still fanning himself in a fit of overreacting. Lestrade raised an eyebrow at the drama queen. Sherlock never remembered his name.

"Oh?" he asked.

"The stubby one told him to do it!" Sherlock said with horror.

Dean lunged at the meat suit. "What did you call me?!"

Lestrade tackled Dean, as well, the crowd helping to keep the brothers rallied. "So I guess violence runs in the family?"

"Shut up!" said Dean.

"This is your fault, you know," Sam said bitterly.

"My fault? I'm pretty sure any demon possessing anyone is on the demon, not me," Dean replied.

"Every hunter knows that demons are drawn to vessels with strong emotional outputs, especially when they have little control over them."

"Yeah, whatever."

"I'm just saying you pushed him. You practically attacked the basis of his beliefs and-"

"I get it, okay?!"

The Winchester brothers had been tied up in the bathroom as they waited for Scotland Yard to arrive.

"The real issue here is how are we going to get out of this mess? When they see we're from America and contact them, we will be sent into the FBI's custody…"

Sam cringed. "Yeah, I'd rather not go through that again."

Dean nodded and looked around the room for any sign of an escape. "But everyone thinks that you…Hey, what's that?"

"Are we having fun yet?" Sherlock walked into the bathroom to have some "closure" with the people who tried to kill him, as everyone at the wedding thought. "See what happens when you resist me? Things get messy with almost no effort on my part. You shouldn't have put up a fight." The demon laughed at the captive's faces. "No need to be so hateful."

"Yeah, coming from a demon," Sam flashed the inherited sarcastic smile. Sherlock's grin faded and he lunged into Sam's face.

"Ha." Sherlock tapped Sam's nose. "Fear," he chuckled.

"We aren't afraid of a bottom-feeding demon like you," said Dean.

"No?" Sherlock humored him. "Clenched jaw, sweat beads on brow, an increase in blood pressure and breathing, and swallowing saliva. All signs of fear, which happens to be my favorite."

"Favorite what?" Sam asked. Without answering, the demon wiped his fingers along Sam's forehead and licked the sweat off them.

"Dude," Dean contorted his face. "Gross."

"Well," John Watson cleared his throat loudly as he shut the door behind him. "What's going on here?" The demon flashed his black eyes back to Sherlock's sky ones and swung to face the groom.

"John! How long have you been standing there?"

"Long enough…" John smiled. "Long enough to know you have a thing for Sam."

"Uh…I," the demon stuttered, glad that John hadn't seen anything.

"However sick and twisted it is to have a thing for someone who tried to kill you," John continued, frowning.

The demon's fake embarrassed smile faded. What did this worm know? He seemed suspicious of Sherlock's behavior, but what did he have to fear? John couldn't possibly believe in the supernatural. If he did, he hadn't told this vessel about anything he knew. So it seemed unlikely that John could know he was a demon possessing Sherlock Holmes, considering his vessel's records ranked John as a high priority. If John meant a lot to Sherlock, it was probably true the other way around, seeing how humans are. He would have informed Sherlock of the supernatural before now if they were so close, right?

"I'm sorry this had to happen on your wedding day, John," frowned the demon. "You should really get back to the party, right?"

"I don't mind."

"Mary must be very upset. You should get everyone to the dining area and continue with the festivities."

"I don't think-"

"It's decided then," Sherlock clapped his hands together. "You go about your wedding celebrations and I'll take these two to the Yard myself. I always was more comfortable at work, you know tha-"

In a flash, John Watson whipped out his flask and threw the contents onto Sherlock's face. The demon screamed and put his hands over the burns, steam fuming from in-between his fingers. John gave the demon a hard shove and he stumbled backwards into one of the stalls.

The demon laughed as his eyes flicked black, "Hehehe…You'll pay for that, you bloody imbecile." He plunged towards the door of the stall, only to be knocked back as if hitting an invisible brick wall.

"Will I?" John sneered. He pointed towards the ceiling above Sherlock's head, which had a thick devil's trap drawn on the ceiling with lipstick.

"Nice," Dean grinned. "You are a genius."

John untied the Winchesters. "I'm not the one used to hearing that," he said, glancing at his friend's hijacked body.

"So, what are we going to do with him?" Sam asked.

"Haha! It doesn't matter, does it?" the demon taunted. "I've already called them. They're coming!"

"Who's coming?" John asked.

"My brothers and sisters! Ha ha!"

"Don't listen to him, he's lying." Dean warned.

"Am I?" Sherlock giggled.

"Sam? Dean? What does it mean? More are coming?" John asked in a fluster.

"It's lying, John! Demons lie," Dean reassured him. "All they want is chaos."

John nodded and his sweat dripped from his forehead to the cold tile floor. He held out his hand. "Give me the blade, Sam."

"What? No! That will kill Sherlock!" Sam refused.

"I KNOW!" John yelled. He took a deep breath. "I know…but what other way is there to kill this bastard?"

"There isn't one! We either use the demon blade or exorcise him."

"Oh, I'd love a run through the park right about now!" Sherlock mocked from his trap.

"Exorcism, not exercise," Dean emphasized, glaring at Sherlock for a moment. "Won't kill the demon, but he'll be sent back to hell where he belongs."

"I know what an exorcism is," John defended himself. "I simply don't think that any demon who infiltrates my wedding and possesses my best man should not live to tell the tale."

"Hey, I get where you're coming from," Dean agreed. "I'd want the same thing. But that would mean giving Sherlock up. For me, that wouldn't be very difficult. But you seem to have a strong connection with him."

John sighed. "It seems that we only have one option now."

"What's our only option?" a voice interrupted. Everyone looked at the woman who had snuck in with the same stealth of her husband.

"Mary," John greeted his new wife with a kiss. "Did you do everything I asked?"

"Everything's in order," Mary smiled.

"That's my girl," John kissed her again, not stopping this time.

"Alright, alright. Save it for the honeymoon, lovebirds," said Dean.

"What do you mean by 'do everything you asked'?" Sam inquired. "What are you planning?"

Mary walked over to Sherlock, stuck in the devil's trap she had drawn on the ceiling. "Well," she cooed. "We're planning to get rid of this devil, of course." She turned back towards the hunters. "And I meant the demon, not Sherlock." Dean laughed loudly.

"Dean," Sam hit his back.

"What? That was funny."

"I've had everyone return to the dance floor under the impression that you two have already been taken away," Mary stated. "They won't hear anything that happens in here and it will be clear for you two to sneak out quickly after we're done," She added sass to her tone. "No demon is going to ruin my wedding day."

"Well, I'll be damned!" Dean exclaimed.

"Yes, you will!" Sherlock taunted yet again.

"You sure have married a capable woman, John," Dean finished, ignoring the snickering demon.

"I've explained everything to Lestrade. He was hesitant to listen to me at first, but he has an open heart and mind. Plus it is my wedding day after all. Perhaps when Sherlock confirms it all he will believe me. I've also scraped these up." Mary handed the Winchesters fake British I.D.'s with their pictures and fake names on them. "Those should get you on the first flight out of London."

Sam gawked. "How-"

Mary held her hand up. "I have friends in low places. Plus I called in a favor."

Dean whistled. "Capable and mysterious."

"How do you know about all this stuff in the first place?" Sam asked.

"Why wouldn't I share this with my wife? She's family, she deserves to know," John replied.

"Yeah…" Sam mumbled and shot a glance at his brother. "There shouldn't be any secrets with family, huh?"

"Plus, she's better at hunting than me, anyways," John added.

Mary shook her head. "Oh please, dear, you're the marksman of the century and we all know it."

"Well, let's get to it then," said Dean, getting back to the task at hand.

"Wait," Sam stopped him. "There's a high possibility Sherlock won't survive this. Most exorcisms take the vessel along with the demon."

"Sherlock his strong," John said quietly. "I have to believe he'll pull through."

Mary gently put her hand on her husband's shoulder. "He'll be okay, John," she encouraged. John put his hand over hers and took a deep breath.

"Let's do it," he said. They all circled around the entrapped demon writhing in Sherlock Holmes' skin.

"You're all going to pay for this when I come back!"

"Yeah, that's if you pass the Demon Exam, newbie," Dean sneered.

John stood close to his best man. "Listen, Sherlock,"

The demon interrupted him. "Hm, he's not available at the moment, can I take a message?"

"Sherlock if you can hear me," John continued. "I just-if this all goes wrong and you end up-" his voice cracked. "I just want you to know that I'm sorry for not telling you sooner about everything I do. I wanted to, but I knew you wouldn't believe me-"

"He thinks you're a terrible person for hiding this from him," spat the demon. "He said he'd rather die than survive only to live with you."

"I want you, Sherlock Holmes, to know that…you are the best friend I ever had or will have." John Watson sniffed and stepped back to join the others, a single tear crawling down his face.

"Aw, how sweet," cackled the demon. "Too bad he-"

"Exorcizamus te, omnis immundus spiritus, omnis satanica potestas…" the exorcism began, all four reciting it in unison. Sherlock screamed and spat curses before finally…

"Audi nos!" the group finished. The inky smoke rocketed from Sherlock's belly like vomit and poured out his mouth. Sherlock's eyes opened in shock and he gasped for air. John ran to catch his best friend's weak, collapsing body.

"Is he okay?" Same asked desperately.

"You both need to leave now, there's no time," Mary said sternly.

"But-"

"Lestrade's covering for you, go now! We'll update you on a secure line when it is safe."

"But what if more come? We have to help-"

"We can handle ourselves. Remember it was us who saved you, not the other way around."

"Come on, Sam. Let's go!" Dean dragged his brother out the door.

"Sherlock? Sherlock! If you bloody leave me, I swear to god-"

Sherlock groaned, his face betraying the pain he was in. "John…?"

"Yes! Yes, it's me. I'm here," John cried.

"I-" Sherlock muttered.

John shook his head. "No, don't speak, you have to rest. I'm going to patch you up, so just hold tight."

"I-I'm your- b-best friend?" he asked with a glaze of happiness in his eyes before drifting into unconsciousness.
